OWNER’S MANUAL
Innovation • Professionalism • Service
Thanks for choosing HCP paddle wheel aerators.
►Please read following detail and have comprehensive understanding for all content in this
instruction manual before your installation.
►Please keep this instruction manual in proper place and it can be accessed easily by operators,
technicians, and inspectors.
►Please contact the local dealers or HCP directly, if any damage found before your installation.
►The gross weight excludes cables.
Note: In order to avoid people injury, the operation shall be applied in
safe and correct way, and comply with the following warning and
attention issues.
I. SAFETY INSTRUCTIONS
WARNING‼
►It is suggested to assemble safe and qualified control panel with HCP paddle wheel aerators, and
equip with leakage circuit breaker and connect with the ground wire (GREEN) properly. It will
prevent from fire or people injury due to electric shock, when the motor malfunctions and it results
in power leakage.
►The operators are prohibited to enter the pool, when the aerators are under operation. The power
should be turn off before operators entering the pool to avoid power leakage.
►Please turn off the power immediately in case of any abnormality or malfunction occurs when
power connecting.
►Please do not press, strain, or modify cables, and never use cables as ropes to pull the aerators. It
may cause cables damage or short circuit, and even result in electric shock or fire disaster.
ATTENTION‼
►Only trained technicians and engineers are allowed to provide maintaining or repairing service.
WARNING‼
►Impellers will be damaged if operating the aerators on dry ground.
People may get injured if ignoring the warning.
►Keep away from the rotating and heat parts when the aerators are under operation.
►Please do not stand on aerators due to the limited buoyancy of floats, otherwise it may cause
people falling or aerators overturning.
ATTENTION‼
People may get hurt or aerators may be damaged, if ignoring the note.
Note: Though HCP always put quality and safety as first priority for our
all products, and try to detail all safety instructions in this manual, it's
still suggested that operators or repair technicians should well take care
of themselves when operating the aerators.

ATTENTION‼
ATTENTION‼
►In order to avoid the risk of electric shock, please do not connect the power cable with motor
before processing the installation of paddlewheel aerators.
►If any components shortage is found before processing the installation, please contact the
local dealer or HCP immediately.
►Please examine if lubricants which store in the reducer are enough. You can open the oil-hole
and visually inspect the height of lubricants in the reducer. The height should not be lower
than the point of gear inside the reducer.
►Please must follow up the correct steps of installation. Any improper installation will result in
aerators damage or poor efficiency.

►In order to avoid the risk of electric shock, please turn off the power before connecting the
cables.
►Please ensure the voltage and phase on nameplate which corresponds with your local
regulation and process the wiring according to the indication on nameplate. The improper
power and wiring will cause motor damage.
►It is suggested to equip with control panel when operating the aerators. Only qualified
technicians can process the wiring and they should strictly follow up the related safety
electrical regulation.
►Please ensure to supply stable and sufficient rated voltage, and only 10% will be allowed for
voltage altering, but motors may burn otherwise.

VI. REGULAR INSPECTION ITEMS
1. OPERATION TEST: After completing the assembly and wiring, please process the operation test
on the dry land, and the aerators should be kept away from the ground by 15cm. After assuring
the aerators can operate properly( Please refer to figure 1 for the correct impeller rotating
direction, and one minute will be enough for testing time.), please disconnect the power.
Impeller Reversal: Please adjust the wiring(see figure 2), if impellers operated in reverse direction.

If aerators will be stocked more than 6 months in warehouse, please note the following
issues especially.
►Please do not store aerators outdoors, and the warehouse should be kept dry and dust-free,
avoiding direct sunlight.
►The proper temperature should be maintained at 5°C~ 40°C
►If aerators will be stocked more than 2 years, the detailed inspection must be processed
first, like bearings, seals, and lubricants. If any damage or rust on spare parts is found, it
should be replaced before installation.
1. INSPECTION AND MAINTENANCE
Before aerators are dispatched from our factory, the lubricants are filled in the gear box already.
After 250 hours operation, it is suggested to replace and refill sufficient lubricants, and afterward,
lubricants also should be refilled yearly. Besides, please process the regular inspection and
maintenance based on the below items for longer operation life.

Daily
1. To inspect the amperage if it fits the rated range.
2. To inspect the voltage under operation if it's within the safe range.( +-10% of
rated voltage)
3. If any abnormal sound appears during the operation, please disconnect the
power immediately.
4. If discovering any adherent substance on impellers, please remove it by proper
way. If any impellers deformation found, please replace it immediately.
5. If floats are degrading, cracked or damaged, please replace them immediately.
Monthly
1. To inspect if oil seal gets degrading or cracked. The ventilation hole should be
kept unobstructed.
2. To inspect if bolts for all parts get loose.
3. If cables are damaged, please replace them immediately.
4. Please smear anti-rust oil on movable joint sets and shafts.
Yearly
1. To replace lubricants: after 4500 hours operation or 12 months(To depend on
which comes first)
2. To replace oil seal: The specialized knowledge and tools are necessary when
replacing oil seal. Please contact our local dealer or HCP directly.
3. If any damage found on bearings and shafts, please replace them immediately.
4. If aerators are always under continuous operation, it is suggested to invite
professional technicians to process the inspection and maintenance.

2. INSPECTION OF SPARE PARTS: After finishing the operation test, please re-arrange the
inspection for all spare parts if any loose or abnormality.
3. INSTALLATION OF AERATORS: To place the aerator into the pool and fix it with nylon ropes or
rods. If the aerator is never fix stably, it will cause equipment damage or poor efficiency for oxygen
supply due to aerators drifting.
4. CABLES FASTENED: Cables must be fastened securely and prevented from affecting the
impeller operation.
5. LOCATION OF SET-UP: The aerator should be placed 1 meter away from the shore at least and
the impeller should sink in the water by the depth of 7-9cm. It is suggested to arrange aerators as
following figures, so that the oxygen will flow and spread adequately.
6. TO START THE OPERATION: After assuring the aerator is installed appropriately, please turn on
the power to start testing. If any abnormality is found during the test, please turn off the power
immediately and pull aerators back to the shore for the further inspection. It is prohibited to stand
in the water or on the floats to inspect the aerator when operation.

2. LUBRICANTS
Before refilling new lubricants, please empty and clean old lubricants when replacing lubricants. If
any overheating(over 80°C) due to malfunction or other mechanical problems is discovered, please
turn off the power immediately and lubricants replacement only can be processed after
troubleshooting. When processing the regular lubricants replacement, it is suggested to reach the
height of gear inside the reducer. (Bevel gear box with 1600cc, turbo gearbox with 2000cc).
Excessive or less amount will affect the efficiency of reducer. Please be advised to use same grade
lubricants when processing maintenance, and it will affect the operation life and efficiency if mixing
different grades of lubricants. Recommended type of lubricants is ISO VG 320 or other same grade
lubricants.
